I donât like the look of my pterygium. If there is no recurrence, it is highly likely that within 6 months after the surgery, you will probably not be able to tell which eye has had surgery.
A methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms â CH 3. The group is often abbreviated Me.Such hydrocarbon groups occur in many organic compounds. It is a very stable group in most molecules. methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms â CH 3. The group is often abbreviated Me.
The formyl group is a functional group, with the structure R-CHO, consisting of a carbonyl center (a carbon double bonded to oxygen) bonded to hydrogen and an R group, which is any generic alkyl or side chain. The group without R is called the aldehyde group or formyl group.ecause of resonance stabilization of the conjugate base, an Î±-hydrogen in an aldehyde (not shown in the picture above) is far more acidic, with a pKa near 17, than a C-H bond in a typical alkane (pKa about 50).
